Fully rewrite the software for java7

The software has fully been rewritten.

It is now optimized, is based on Java7, don't use the Swing Application FrameWork, or the zip library.

Many bugs have been fixed. The interface is similar.

Some bugs still exists (mostly on Mac OS X) : 
- If the software is not launched from terminal, the files with accent (é, à, è, ù, ...) won't appear (or won't be readable)
- The trackpad now only allow to move in the image displayed. We can't magnify / rotate / change image with the trackpad anymore.
Theses 2 main bugs seems to be related to java being switch from Apple (java6) to Oracle (java7) which still don't have implemented everything.
